QWERTY MIDI

QWERTY MIDI computer keyboard controller in fourths layout
QWERTY MIDI is a browser based computer keyboard MIDI controller. It particularly supports an isomorphic 4ths layout, which is more natural to play and easier to learn. MIDI can be sent through inter-app or network MIDI on macOS devices.

MIDI channels, sustain and latching
